General information
Applies to vehicles: with d iesel e ng in e
On vehicles w ith select ive catalytic reduction,
an urea solut ion (Ad Blue) is injected into the
exhaust system befo re a nitrogen oxide cata ­
lytic converter to reduce nitrogen emiss ions .
The AdBlue is stored in a separate tank in the
ve hicle. The Ad Blue usage accounts for ap­
prox imately 0 .5% to 1.2% of the diesel fuel
that is used .
You must refill the Ad Blue or have it refilled by your authorized Audi dealer or qualified
workshop as soon as the Ad Blue refill mes ­
sage appears in the instrument cluster

Fa st charging the b att ery (charging rate
abo ve 14.8 Vo lt s)
Fo r technical reasons do not use a batt ery
charger that uses vo ltage g reater than 14.8
Volts to charge your vehicle's battery.
A WARNING
-
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a fro zen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first .
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze .
- Charge the battery in a well ventilated
area . Keep away from open flame or elec­
trical spark . Do not smoke . Hydrogen gas
gene rated by the battery is exp losive.
- To reduce the danger of explosion , never
co nnect or disconnect cha rger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
t ent technicia n w ith the proper eq uip­
ment.
- Battery a cid that may spill d uring charg­
ing should be washed off wit h a solution
of warm wa ter and ba king soda to neu ­
tralize the acid .
CD Note
Never use a fast charge r as a booster to
s tart the engine. This will se rio usly d am­
age sensitive elect ronic components, such
as control units, relays, radio, etc., as we ll
as the battery charger .
Checking and fillin g
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
In telligen t energy managemen t in your vehi­
cle is responsible for distributing the electri ­
cal ene rgy throughout your vehicle
¢ page 202. The intelligent energy manage­
ment system will keep the engine battery
c h arged better than vehicles without this sys ­

changed the battery, we recommend that you
insta ll batteries of the same type and m anu­
facture only (the same as those installed at
the time your ve hicle was delivered) . Specif i­
cat ions are listed on the battery housing . Your
authorized dea le r must code the battery in
the energy management system to enab le you
to use the ene rgy manageme nt func tions cor ­
re ct ly afte r replacing the battery.
The new battery must have the same capacity,
vo ltage
( 1 2 volts), amperage, const ruction
and plug seal ing .
When installing the battery, make sure the ig­ nition and a ll elect rical consume rs are switch­
ed off .
CD Note
- Make sure the ventilation hose on the
side of the battery is connected, other­
w ise fumes or battery a cid ca n leak out .
- Veh icles with the Start-Stop-System* are
e quipped with a spec ial cycle-p roof AGM
battery. Install ing a d iffe rent type of
ba ttery c an cause problems in the vehi ­
cle e lectrical system. Whe n replacing the
vehicle battery, always install one w ith
the same specifications as the origina l
battery.
